from about 50m. as he fired, it stepped and thus got a gut hit. It ran off jumped a fence. Some of its protruding intestines got caught on the fence and the animal gutted itself as it ran another 50 ft. The .72" bore diameter of the 12 ga slug has almost 3x the frontal area of a .4570, yet the animal not only could run, it could jump a fence. Without the guts being caught on the fence, it woul have run much further and in thick brush, especially in the evening, it would probably have had coyote piss all over it. like garand on prom night. Unless it's a .50 BMG softpoint, big bore means nothing except the lack of rapid fire, lack of range, vulnerability to the wind and animal movement and ridiculously overpriced guns, ammo and reloading components. At least the shotgun is useful for other things. The big bore rifle is not.
